wait wait the shaft doesnt contain liquid metal?

Sir , how the raping system is working

Will the charge not fall to the bottom of the furnace as soon as dumped from top? Why does it descend slowly? Is it because of heavy hot air blast?

Nice work, the animations really help to explain the process. Plus the music was great and I was dancing for part of it.

So we can't make steel without first using gas or coal?

I am just here cause the novel I am reading mentioned this technology and tried to explain it. But I found the description hard to understand.

1:19 The air leaving out the top does not look so clean.

I see why the old steel mills shut down in USA.

Genuinely couldn't use this for a lesson, with that music in. It's almost like a badly mixed track where the vocals sit underneath the instrumental. Great content, awful audio.

Hello

i like apple!!!

I currently work on dust collectors and they can get crazy dirty depending on what type of material your filtering out

Carbon content of steel is not 2 to 4%. It is much lower in most all steel grades. A 2% carbon steel would be too brittle for much use. A 4% carbon would be iron not steel.

Very cool

Fucking music makes it almost useless.

I wonder if, with sufficient heat, raw ores could be separated by boiling them into a gas, and then condensing them to a liquid... based on their boiling points. Fractional Distillation of Metals?

Can we say that the direction of the magnetic field in a solenoid is the same as the direction as the current in it?

3:20 - _"...combustion _*_of oxygen_*_ in the furnace"_ - ??! Or should it be "combustion CAUSED BY oxygen"? People, this animation was supposedly/ apparently produced by Swansea UNIVERSITY! And NOT by "Swansea City A.F.C.", right? Why then such a blunder? Repeat after me: "Oxygen does not 'burn' - it makes other things burn" - and again, "Oxygen does not 'burn' - it makes other things burn" - and again, "Oxygen does not 'burn' - it makes other things burn" - and again... till it gets through. And, oh, BTW - there's one exception, actually - OF2, or oxygen fluoride - NOT fluorine oxide, as in this marriage the fluorine is the "oxidiser" - but still, someone please check the script BEFORE recording the narrative, would ya? And then, 3:33 - _"The oxides combine with the calcium in the quicklime to form their RESPECTIVE CALCIUM OXIDES..."_ ?? But quicklime IS a calcium oxide, CaO, so...? Someone please translate it to plain and factually correct English "can or not"? Jeez... "Which then float on the surface of liquid steel, constituting (...??) constituting molten slag" also sounds like "modern education shining through"... How about "which then, being less dense, float as so-called slag on the surface of molten steel" - ? And then... A nit picking, one may say, but showing white-hot slag and steel as black, "tar-like" goo does strike me as odd, to say the least. How about RED, or bright orange? Huh?

To my knowledge, steel is tapped before slag.

Hello can i have your email i have some questions

anybody ever built a electro cyclone?

Can this be used for ceramics?

Hi, could I use part of this animation in my next video? Thanks a lot

whats the xp/h for iron?

Every intercept length line have to have the same measure?

Wonderfully presented

Great video, Thank you, sir!... can you explain how we analyse the tensile data like decreasing or increasing values and the material behavior if we make a comparison

what voltage and current do they run at????

Thanks for the clip. ❤

Thank you

Nice demonstration, thank you!

One of my favourite Seinfeld episodes.

'Promo sm' 😩

Very helpful for my history presentation.

Мы на уроке Английского это смотрели

I worked at two EAF shops in NJ for decades. Instead of direct reduced iron, in order to boost the carbon for high carbon grades we added to the steel scrap either coal, coke, graphite or high carbon railroad rails instead. Also, to supplement the arc heat in the cold spots we had oxygen/natural gas burners. Supersonic Oxygen was injected through a lance through the slag door.

what if we want to use for dendrites? like eutecitc snBi microstructure and want to study phase size distribution. I'll be really thankful if you could help

how did you color your image? each grains different color.

Great video. Are the links already dead?

Sounds like the don’t use any kind of shielding gas, just flux.

Thank you for the useful video! I have a question, I still don't understand how you determine the yield stress. I'm also working on the discontinuous yielding case; we usually determine it by the lower yield strength. Why in this case you determine the yield stress as the region when it changes from elastic to plastic deformation? Not based on upper yield strength or lower yield strength? Thank you!

Brilliant.

It seems that it would lose efficiency in the molten steel because it conducts better than air

Sir in the video Spiegeleisen is not added

Thank you for this! Helped me a lot. Just a question: if you don't have the software you used in the video (i.e. no line to drag with the same angle as the gradient of the elastic region), how can you calculate the elastic + plastic strain to failure using Excel?

Great Video! and Great Efforts Highly Appreciated! May i ask you for the raw data from the machine for 1 ductile and 1 brittle material so i can do the analysis myself ?

What a really clear video, many thanks for sharing and taking the time Dr. Michael.

Great video!
